Hi,

I tried the devices /dev/hs00 - hs03 with a cheap taiwan multi port 
serial card in polled mode. But polled mode is not satisfying.
So I'm looking for an already existing device driver that is able
to use interrupts (only poll the 4 UARTS if an interupt occured).
If not I have to do the writing on my own.
The existing device drivers are too slow so I also want to rewrite
the /dev/com...  so that they are able to use the 16550 with its 
larger FIFO. I noticed that 9600 Baud on a 10 Mhz 286 is too fast,
but works on my 386/33 Micronics. But what to do if you want to use
a Traily with 19200 Baud ?

Thanks for hints

Joachim
